Had tried alot of things to keep my rescued mutt off my sofas, this is the only thing that has worked.

Pros: Just put on static electric training collar and put zone tranmittor in area that you don't want your dog; and the dog's behavior is changed easily and painlessly.

Cons: None that I have found

This product works using a collar for the dog and a small appliance about the size of a smoke detector. You place the appliances where you want the dog or cat to be restricted from and if they come too close their collar is sent a small warning shock. This item uses sound waves. The Innotek system can be used wherever it is needed and uses two standard silver oxide batteries made by Sony. Now easily keep your pet away from your trash, your plant or anywhere else that you would prefer them not to be.

Pros: May restrict pets

Cons: Delivers shocks to pet

I wasn't aware that this product was out there. It sounds like an effective, safe way to train a dog to understand its boundaries.

Pros: Keeps pets off furniture

Cons: A little pricey
